A satellite is moveing in a circular orbit around the earth. The total energy of the satellite is `E=-2xx10^(5) J`. The amount of energy to be imparted to the satellite to transfer it to be orbit where its potential energy is `U=-2xx10^(5)J` is equal to ................

Answer

`1xx10^(5)J`

Explanation

`E_(1)=(U_(1))/(2) rArr E_(2)=(U_(2))/(2) = -1xx10^(5)J rArr E_(1)=-2xx10^(5)J`
So `Delta E=E_(2)-E_(1)=1xx10^(5)J`
